"Elodea canadensis" Michx a l'embassament de la Torrassa: rècord de fondària per a una fanerògama d'aigua dolça

Elodea canadensis Michx at the Torrassa reservoir ( Pyrenees, Catalonia): depth record for a freshwater phanerogam . The submersed vegetation of Torrassa reservoir (Pyrenees region) was extensively surveyed. It was wholy dominated by Elodea canadensis Michx, that although weakly, extended even to the deepest part of the reservoir (14 m). This represents a new maximum depth penetration for freshwater angiosperms with lacunae.
